An Analysis of Flight Measurements in the Wake of a Jet Transport Aircraft
Peak velocity vectors measured in the transverse plane of the wake of a Convair 880 aircraft were found to be four times as high as anticipated. The peak velocities are shown to occur in small intense vortices which are separate from the main tip vortices These exist up to 30 seconds after generation. The main tip vortices are shown to have a core size which is roughly of the size anticipated but whose diameter does not increase significantly up to 30 seconds after generation.
